I have a 2009 328xi 4 door sedan, i need shocks all around, im also running H&R sport springs. I want to go with bilsteins. Im shopping on Amazon and i just wanted to know does the price look about right and also will standard bilstein shock perform well with my H&rs?

I think you need Bilstein b8s since you are on H&R sport springs..

Well, I would imagine that the install would not go so well. I am not sure on specifics , but I would just get the b8s to prevent any further problematic situations. If you read on the Bilstein website it should tell you why you should use B8s if you are on h & r sport springs..

If you look at their FAQ page is says the B8's will lower up to 50mm and the B6 up to 30mm.

Down to which lowering level can I go with BILSTEIN B6 sports shock absorbers (not shortened) in conjunction with shorter springs?
Down to 30mm. That is what is typically offered for new vehicles straight from the factory. Any lower and a shock absorber with a shortened stroke has to be fitted, so that the spring tension - which ensures the required distance between the car body and the wheel - is maintained, whatever the driving situation. Otherwise the spring may slip out of its fitting and the vehicle will abruptly go out of control.

That little otherwise part does not sound too good.

I have read the B8 goes with HR. I have B6 on stock springs..
